摘　　要：对无线网络通信信息传输隐私的保护,能够有效提高无线网络通信的安全性。对通信信息传输的隐私保护,需要对信息传输进行加密,通过散列函数将核心信息转换成信息摘要,完成对信息传输隐私的保护。传统方法对系统随机分配密钥进行二次Rijndael加密防护,给出通信中信息加密传输策略,但忽略了将核心信息转换成加密信息摘要,导致保护效果不理想。提出基于改进哈希的无线网络通信中信息加密传输方法。利用椭圆曲线密码体制将加密的信息描述成椭圆曲线的点,通过散列函数将函数将核心信息转换成信息摘要,通过私钥对信息摘要进行加密,利用分块内容的哈希值生成分块对称密钥,得到明文分块与密文分块之间的一致性,以此为依据完成对无线网络通信中信息加密传输。仿真证明,所提方法加密稳定性较高,大幅度提升了无线网络通信中信息传输的安全性和稳定性。This article presents a transmission method for information encryption in wireless network communica- tion based on improved Hash. Firstly, the encrypted information is described as elliptic curve point by using elliptic curve cryptosystem, then function core information is transformed into information abstract via hash function and in- formation abstract is encrypted by private key, and then block symmetric key is generated by using hash value of block content, thus consistency between plaintext block and ciphertext block is obtained. Finally, information en- cryption transmission in wireless network communication is completed. The simulation results show that the method in this article has high encryption stability. It can greatly improve security and stability of information transmission in wireless network communication.
